Microsoft sql server 2014 business intelligence 64-bit free.What happened to SQL Server Data Tools in SQL Server 2014?

Exclusive lock grants the user exclusive access to the data—no other user can access the data as long as the lock is held. Shared locks are used when some data is being read—multiple users can read from data locked with a shared lock, but not acquire an exclusive lock. The latter would have to wait for all shared locks to be released.

Locks can be applied on different levels of granularity—on entire tables, pages, or even on a per-row basis on tables. For indexes, it can either be on the entire index or on index leaves. The level of granularity to be used is defined on a per-database basis by the database administrator. While a fine-grained locking system allows more users to use the table or index simultaneously, it requires more resources, so it does not automatically yield higher performance.

SQL Server also includes two more lightweight mutual exclusion solutions—latches and spinlocks—which are less robust than locks but are less resource intensive. SQL Server also monitors all worker threads that acquire locks to ensure that they do not end up in deadlocks —in case they do, SQL Server takes remedial measures, which in many cases are to kill one of the threads entangled in a deadlock and roll back the transaction it started.

The Lock Manager maintains an in-memory table that manages the database objects and locks, if any, on them along with other metadata about the lock. Access to any shared object is mediated by the lock manager, which either grants access to the resource or blocks it. SQL Server also provides the optimistic concurrency control mechanism, which is similar to the multiversion concurrency control used in other databases.

The mechanism allows a new version of a row to be created whenever the row is updated, as opposed to overwriting the row, i.

Both the old as well as the new versions of the row are stored and maintained, though the old versions are moved out of the database into a system database identified as Tempdb. When a row is in the process of being updated, any other requests are not blocked unlike locking but are executed on the older version of the row. If the other request is an update statement, it will result in two different versions of the rows—both of them will be stored by the database, identified by their respective transaction IDs.

The main mode of retrieving data from a SQL Server database is querying for it. The query declaratively specifies what is to be retrieved. It is processed by the query processor, which figures out the sequence of steps that will be necessary to retrieve the requested data.

The sequence of actions necessary to execute a query is called a query plan. There might be multiple ways to process the same query. For example, for a query that contains a join statement and a select statement, executing join on both the tables and then executing select on the results would give the same result as selecting from each table and then executing the join, but result in different execution plans.

In such case, SQL Server chooses the plan that is expected to yield the results in the shortest possible time. This is called query optimization and is performed by the query processor itself. SQL Server includes a cost-based query optimizer which tries to optimize on the cost, in terms of the resources it will take to execute the query. Given a query, then the query optimizer looks at the database schema , the database statistics and the system load at that time.

It then decides which sequence to access the tables referred in the query, which sequence to execute the operations and what access method to be used to access the tables. For example, if the table has an associated index, whether the index should be used or not: if the index is on a column which is not unique for most of the columns low “selectivity” , it might not be worthwhile to use the index to access the data. Finally, it decides whether to execute the query concurrently or not.

While a concurrent execution is more costly in terms of total processor time, because the execution is actually split to different processors might mean it will execute faster. Once a query plan is generated for a query, it is temporarily cached. For further invocations of the same query, the cached plan is used.

Unused plans are discarded after some time. SQL Server also allows stored procedures to be defined. Stored procedures are parameterized T-SQL queries, that are stored in the server itself and not issued by the client application as is the case with general queries.

Stored procedures can accept values sent by the client as input parameters, and send back results as output parameters. They can call defined functions, and other stored procedures, including the same stored procedure up to a set number of times. They can be selectively provided access to. Unlike other queries, stored procedures have an associated name, which is used at runtime to resolve into the actual queries.

Also because the code need not be sent from the client every time as it can be accessed by name , it reduces network traffic and somewhat improves performance. It exposes keywords for the operations that can be performed on SQL Server, including creating and altering database schemas, entering and editing data in the database as well as monitoring and managing the server itself. Client applications that consume data or manage the server will leverage SQL Server functionality by sending T-SQL queries and statements which are then processed by the server and results or errors returned to the client application.

For this it exposes read-only tables from which server statistics can be read. Management functionality is exposed via system-defined stored procedures which can be invoked from T-SQL queries to perform the management operation.

Linked servers allow a single query to process operations performed on multiple servers. It natively implements support for the SQL Server features including the Tabular Data Stream implementation, support for mirrored SQL Server databases, full support for all data types supported by SQL Server, asynchronous operations, query notifications, encryption support, as well as receiving multiple result sets in a single database session.

NET Framework. Unlike most other applications that use. NET Framework runtime , i. SQLOS provides deadlock detection and resolution services for.

NET code as well. Managed code can also be used to define UDT’s user defined types , which can persist in the database. Managed code is compiled to CLI assemblies and after being verified for type safety , registered at the database. After that, they can be invoked like any other procedure. Most APIs relating to user interface functionality are not available. However, doing that creates a new database session, different from the one in which the code is executing.

NET provider that allows the connection to be redirected to the same session which already hosts the running code. Such connections are called context connections and are set by setting context connection parameter to true in the connection string. NET API, including classes to work with tabular data or a single row of data as well as classes to work with internal metadata about the data stored in the database.

SQL Server also includes an assortment of add-on services. While these are not essential for the operation of the database system, they provide value added services on top of the core database management system. The SQL Server Machine Learning services operates within the SQL server instance, allowing people to do machine learning and data analytics without having to send data across the network or be limited by the memory of their own computers.

The services come with Microsoft’s R and Python distributions that contain commonly used packages for data science, along with some proprietary packages e. Analysts can either configure their client machine to connect to a remote SQL server and push the script executions to it, or they can run a R or Python scripts as an external script inside a T-SQL query.

The trained machine learning model can be stored inside a database and used for scoring. Used inside an instance, programming environment. The Service Broker, which runs as a part of the database engine, provides a reliable messaging and message queuing platform for SQL Server applications. Service broker services consists of the following parts: [40]. The message type defines the data format used for the message. This can be an XML object, plain text or binary data, as well as a null message body for notifications.

The contract defines which messages are used in an conversation between services and who can put messages in the queue. The queue acts as storage provider for the messages. They are internally implemented as tables by SQL Server, but don’t support insert, update, or delete functionality.

The service program receives and processes service broker messages. Usually the service program is implemented as stored procedure or CLR application. Routes are network addresses where the service broker is located on the network. Also, service broker supports security features like network authentication using NTLM , Kerberos , or authorization certificates , integrity checking, and message encryption.

SQL Server Replication Services are used by SQL Server to replicate and synchronize database objects, either in entirety or a subset of the objects present, across replication agents, which might be other database servers across the network, or database caches on the client side. SQL Server supports three different types of replication: [41].

Analysis Services includes various algorithms— Decision trees , clustering algorithm, Naive Bayes algorithm, time series analysis, sequence clustering algorithm, linear and logistic regression analysis, and neural networks —for use in data mining. It is administered via a web interface. Reporting services features a web services interface to support the development of custom reporting applications.

Reports are created as RDL files. A subscriber registers for a specific event or transaction which is registered on the database server as a trigger ; when the event occurs, Notification Services can use one of three methods to send a message to the subscriber informing about the occurrence of the event.

The full text search index can be created on any column with character based text data. It allows for words to be searched for in the text columns. Full allows for inexact matching of the source string, indicated by a Rank value which can range from 0 to —a higher rank means a more accurate match. It also allows linguistic matching “inflectional search” , i. Proximity searches are also supported, i. These processes interact with the SQL Server. The Search process includes the indexer that creates the full text indexes and the full text query processor.

The indexer scans through text columns in the database. It can also index through binary columns, and use iFilters to extract meaningful text from the binary blob for example, when a Microsoft Word document is stored as an unstructured binary file in a database. The iFilters are hosted by the Filter Daemon process. Once the text is extracted, the Filter Daemon process breaks it up into a sequence of words and hands it over to the indexer.

The indexer filters out noise words , i. With the remaining words, an inverted index is created, associating each word with the columns they were found in. SQL Server itself includes a Gatherer component that monitors changes to tables and invokes the indexer in case of updates. The FTS query processor breaks up the query into the constituent words, filters out the noise words, and uses an inbuilt thesaurus to find out the linguistic variants for each word. The words are then queried against the inverted index and a rank of their accurateness is computed.

The results are returned to the client via the SQL Server process. It allows SQL queries to be written and executed from the command prompt. It can also act as a scripting language to create and run a set of SQL statements as a script. Such scripts are stored as a. It also includes a data designer that can be used to graphically create, view or edit database schemas.

Queries can be created either visually or using code. The tool includes both script editors and graphical tools that work with objects and features of the server. A central feature of SQL Server Management Studio is the Object Explorer, which allows the user to browse, select, and act upon any of the objects within the server.

It includes the query windows which provide a GUI based interface to write and execute queries. Azure Data Studio is a cross platform query editor available as an optional download.
